8263412: ClassFileInstaller can't be used by classes outside of default package #2932

wants to merge 4 commits into from

@iignatev iignatev commented Mar 11, 2021

Hi all,

could you please review the patch which moves ClassFileInstaller class to jdk.test.lib.helpers package?
to reduce changes in the tests, ClassFileInstaller in the default package is kept w/ just main method that calls jdk.test.lib.helpers. ClassFileInstaller::main.

from JBS:

ClassFileInstaller is in the default package hence it's impossible to use it directly by classes in any other package. although ClassFileInstaller is mainly used directly from jtreg test description, there are cases when one needs to use it in another "driver" class (e.g. to reduce boilerplate), yet to do. that these driver classes have to either be in a default package or use reflection, both approaches have drawbacks.

to solve that, we can move ClassFileInstaller implementation to a package, and to avoid unneeded churn, keep package-less ClassFileInstaller class which will call package-full impl.

the need for this patch has raised as part of JDK-8254129.

  • :jdk_svc against {macos,windows,linux}-x64
  • test/hotspot/jtreg w/o applications and vmTestbase directories against {macos,windows,linux}-x64

The CDS test changes look good to me. It seems they are just adding a single line of import.
